ubsan: m32c: left shift of negative value

There are probably a lot more of these still here.

cpu/
	* m32c.cpu (f-dsp-8-u16, f-dsp-8-s16): Rearrange to mask any sign
	bits before shifting rather than masking after shifting.
	(f-dsp-16-u16, f-dsp-16-s16, f-dsp-32-u16, f-dsp-32-s16): Likewise.
	(f-dsp-40-u16, f-dsp-40-s16, f-dsp-48-u16, f-dsp-48-s16): Likewise.
	(f-dsp-64-u16, f-dsp-8-s24): Likewise.
	(f-bitbase32-16-s19-unprefixed): Avoid signed left shift.
opcodes/
	* m32c-ibld.c: Regenerate.
